New Research

The following new research studies reported by the Federal Highway Administration's (FHWA) Office of Research and Development are sponsored in whole or in part with federal highway funds. For further details on a particular study, please contact Bob Bryant, editor of Public Roads, (202) 493-3468.

NCP Category A -- Highway Safety

A.5: Highway Safety Design Practices and Criteria

Title: Highway Safety Design Model -- Data Collection and Analysis

Objective: To develop a prototype interactive highway design model for evaluating the safety impacts of alternative designs. The model will be based on the results of previous FHWA and National Cooperative Highway Research Program (NCHRP) studies or best current practice in areas with missing data.

Contractor: Pragmatics Inc.

Expected Completion Date: May 1996

Estimated Cost: Estimated Cost: $406,638

Title: A Criterion of Testing the Goodness of Fit of a Model

Objective: To conduct computer simulation of different functional forms and to compare the R-square test method and the Akaike Information Criterion (AIC) to determine the goodness of fit. The literature indicates that R-square as a test of the goodness of fit of a model is sometimes misleading. A low R-square value does not mean a poor fit. AIC is gaining in popularity in academic circles.

Interagency Agreement: Department of Energy (Oak Ridge National Laboratory)

Expected Completion Date: January 1995

Estimated Cost: $50,000

NCP Category B -- Traffic Operations/Intelligent Vehicle-Highway Systems

B.1: Advanced Traffic Management Systems

Title: Dynamic Traffic Assignment (DTA) and Synthetic Origin and Destination (O-D) Matrices

Objective: To develop a deployable DTA model designed under the 1990 study "Traffic Modelling Needs for ATIS." Since dynamic O-D data is required for input to the model, this study will develop algorithms to create synthetic O-D data. To account for different intelligent transportation system deployment strategies systems, three variations to the original model design will be developed. These deployment strategies include items such as the type and coverage of traffic monitoring and incident detection systems, the type and capability of traffic signal control systems, and the extent of surface street and freeway control integration. This study will also conduct sensitivity analyses regarding the coupling of DTA with traffic simulation models of different resolution to assess the impact of the routing and/or diversion strategies.

Interagency Agreement: Department of Energy (Oak Ridge National Laboratory)

Expected Completion Date: December 1996

Estimated Cost: $5,250,000

Title: Additional Real-Time Traffic-Adaptive Signal Control Prototype Development (U of Arizona)

B.2: Advanced Traveler Information Systems

Title: Development of an In-Vehicle Signing Specification

Objective: To obtain technical support related to in-vehicle signing. Investigations into the technologies and issues associated with in-vehicle signing (IVS) systems will be conducted. Benefit analysis of IVS shall be conducted within the first three months of this task to guide decisions for future efforts.
